Rostrum as long as oculiferous segment, with a constriction 
on each side below, giving it the appearance of being articu- 
lated at this point, acute-conical, with a rosette of filamentary 
processes around the terminal mouth. 
Antenne hairy, stout and swollen, about twice as long as the 
rostrum, tipped with amber color. Basal joints enlarged near 
their attachment. The second joint has a prominent rounded 
tubercle on the lower end, behind which the dactylus closes. 
Ovigerous legs slender, eleven- 
jointed, terminal joint ‘elaw-like, 
trifid. Fifth joint somewhat cla- 
vate, considerably smaller than 
the fourth. The four outer joints 
are armed with three or four stout, 
smooth, curved spines. 
Legs very stout, the three basal 
joints short, overlapping each other 
in an imbricated manner. Fourt

All of the legs bear more or fewer prominent, conical, spiny 
tubercles. These are arranged in longitudinal rows on some 
of the joints, particularly on the fifth and sixth, which appear 
deeply serrate on the external margin. The entire surface of 
the body is rough, and more or less hairy. 
Genital orifices small, on the second joint of the legs.
